Abstract

A re-configurable correlation unit for correlating a sequence of chip samples comprising: 1) a memory for storing the chip samples; 2) a plurality of add-subtract cells, each add-subtract cell receiving a plurality of real bits, a, and a plurality of imaginary bits, b, from a first chip sample; and 3) a plurality of sign select units. Each sign select units receives from one add-subtract cells a first input equal to a sum (a+b) of the real bits, a, and the imaginary bits, b, and a second input equal to a difference (a-b) of the real bits, a, and the imaginary bits, b. Each sign select unit generates a real output and an imaginary output which are respectively equal to one of: 1) the sum (a+b) multiplied by one of +1 and -1 and 2) the difference (a-b) multiplied by one of +1 and -1.

Description

Background technique [0001] Data processors are used in nearly every type of modern electronic equipment, including consumer electronics, industrial machinery, scientific installations, and communication networks. However, the performance and complexity of data processors (or microprocessors) used in different applications may vary widely. The speed and power requirements of a particular application are important in determining the type of data processor used. [0002] The type of data processor used in a software defined radio (SDR) implementation is particularly important. SDR devices use reconfigurable hardware that can be programmed over the air to work under different wireless protocols. For example, an SDR transceiver in a wireless laptop computer can be configured by a first software load to work in an IEEE-802.11x wireless network, and by a second software load to work in a CDMA2000 wireless network. [0003] There are six main types of commonly used data processors...
